How we measure plumbing

See a Plumbing Takeoff in 3D

Fixtures are counted from the hydraulic layout, then cold water, hot water, drainage and vent pipework is measured by system, diameter and level — with valves and fittings added, so the schedule is ready to price.

  1. The hydraulic layout locates the wet areas, the riser and the incoming main, and sets the levels each system is measured on.
  2. WCs, basins, sinks and showers are counted by type, level by level, against the fixture schedule.
  3. Cold water is traced from the meter, up the riser and along each branch to every fixture, measured by diameter.
  4. The hot water unit is scheduled, then flow pipework is measured from it to every basin, sink and shower.
  5. The soil stack, graded branches and fixture wastes are measured by diameter, then the vent pipe through the roof.
  6. Valves and fittings are counted joint by joint, so the pipework schedule is ready to price.

FAQ

Common Questions

More answers on our FAQ page

Sanitary fixtures and tapware, cold and hot water supply, sanitary drainage and vents, below-ground drainage, stormwater, and gas where shown. The scope is confirmed with you before work starts.

Yes. Fire hydrant, hose reel and sprinkler pipework can be measured where it is shown on the drawings. It is reported separately so it can be priced as its own package.

Yes. In-ground drainage is measured from the drainage plans and long sections, by pipe diameter and depth band, with pits, junctions and trench work listed separately.
